To all whom. it may concern.

Be it known that I, J Essa A. NELsoN, citizen of the United States of America, and resident of Ellsworth, Hamilton county, Iowa, have invented a new and useful Gleaner Attachment for Grain-Elevators, of which the following is a specification.

The object of this invention is to provide means for blowing the chaff, silk, husks and other light waste matter fromear corn and other grain during the operation of elevating said grainfor storage.

My further object is to provide means for! adjusting the course and application of air currents to passing grain.

My further object is to avoid accumulations'of waste matter in stored grain, which waste matter interferes with drying and curing of grain and tends to position therein. I My invention consists in the constructlon,

promote decomarrangement and combination of elements hereinafter set forth, pointed out in my claims and illustrated by the accompanying drawing, in which- Figure 1 is a side elevation illustrating the application of my improvement to a grain elevator. Fig. 2 is a plan of the same; Fig. 3 is a detail elevation, partly in section, showing the device adjusted for treatment of cats.

In the construction. and application of the devices as shown, the numeral 10 designates an elevator frame having a drag elevator 11 therein. The frame 10 preferably is formed with spaced bottoms 12, 13, the upper bot tom 12 being employed to carry the grain and lifting portion of the elevator and the lower bottom 13 being employed to carry the return portion of the elevator. A hood 14 is mounted over the upper end portion of the frame 10 and an apron 15, preferably of oiled cloth, is fixed to the lower'margin of said hood and depends on the elevator or on the grain being carriedthereby. A hopper 16 is suspended from the upper end portion.

of the frame 10 and is adapted to receive grain from the elevator. A delivery spout 17 is swiveled to the hopper 16 and is adapt ed to receive grain therefrom and convey it to any desired point of deposit.- An'opening is formed in the head ofthe hood 14, preferably at right angles to the mouth of the hopper 16, and a spout 18 is connected, by anysuitable swivel joint, with saidhood and communicates with the interior thereof through said opening. A chamber 19 is suspended from the frame 10 and a blast fan 20, journaled in-said chamber, is driven by anysuitable gearing to a prime mover, such as the mechanism used to drive the elevator. The upper end portions of the bottoms 12, 13 preferably are perforated and a chute or passage 21 leads from the fan chamber to a point beneath the perforated portion of the lower bottom. A valve 22 may be mounted for manual adjustment over the perforated portion of the upper bottom 12'to prevent oats and similar small grain from falling through said bottom, and

to direct the same to the hopper.

In practical use the fan and elevator are operated simultaneously and as car corn is dumped from the upper end of the bottom 12 and is carried across the perforated portion of saidbottom, a current of air from the fan'through the chute21 passes upward through the perforated portions of 'the bottoms and blows the chafi, husks, silk.and shelled corn, smut and the like waste matter from the ear corn and carries such waste substances and shelled corn across the hood and out through thespout 18 to a placeof deposit separate from the ear corn. When oats are elevated, the valve 22 is placed as shown in Fig. 3 to guide the cats to the hopper, and the current of air enters the frame through the perforations in the lower bottom 13 and passes upward along the bottom 12 and .crosses the hood through the falling oats. During this operation the current of air fans the falling oats and carries light oats, chafl and sticks away through the spout 18. The force of the air blast may be regulated by valves 23 on the entrance of the fan chamber.

I claim as my invention- 1. The combination of a grain elevator havina a hood and perforated bottoms be-' neath said hood, an elevator traveling on said upper bottom and extending within said hood, spouts leading fromsaid hood at angles to each other, and a blast fan acting *jjthrough said'perforated bottoms into said hood 2. grain elevator formed with spaced bottoms and also formed with a hood, an
